Now that I am going to pull the trigger on Kooks LTH's, I need to pick size and accessories. I have read a ton of posts and they all seem to point to 1-7/8" but I was thinking 1-3/4". Any reason I should go with the larger tubes? Do I need gaskets or do the Kooks provide a quality set? How about fasteners? I saw blacksheep-1 didn't like Stage 8's but others swear by them. I will be dropping the K-member so I will have good access.
